China’s CO2 emissions begin declining for first time

/

The world’s largest emitter of carbon dioxide has seen a slight decline in those emissions over the past 12 months, even as demand for power has increased. This is an encouraging sign that the country’s massive investment in clean energy has begun to displace fossil fuels. A new report, published in Carbon Brief, finds that the country’s CO2 emissions have declined by 1% over the past 12 months. In the first quarter of 2025 alone, emissions declined by 1.6% relative to last year.

Solar panels to be fitted on all new-build homes in England by 2027

/

Almost all new homes in England will be fitted with solar panels during construction within two years. Under the plans, housebuilders will be legally required to install solar panels on the roofs of new properties by 2027. The policy is estimated to add between £3,000 and £4,000 to building a home, but homeowners would save more than £1,000 on their annual energy bills, according to the Times.

Renewable energy now handles 40% of global electricity needs

/

According to a new report from U.K. think tank Ember, clean energy accounted for 40.9% of electricity produced worldwide in 2024. The push past the 40% mark was fueled by an unprecedented growth in solar, significant contributions from wind, a recovery in hydropower, and a small rise in nuclear power. China and the E.U. demonstrated the most remarkable increases in clean electricity generation, meeting 81% and 71% of their new electricity demand from renewables in 2024, respectively.

Fossil fuels fall below 50% of U.S. electricity for the first time since the 1800s

/

In a major milestone for climate action, the U.S. hit a new record low for fossil fuels in the electricity mix last month as solar and wind reached a record high, according to new data from global energy think tank Ember. In March 2025, fossil fuels accounted for less than 50% of electricity generated, for the first month on record. The shift meant that clean sources generated more than half (50.8%) of U.S. electricity for the first month on record.

Finland has effectively phased out coal as a source of electricity generation

/

The closure of a coal power plant in Finland today brings the country to the brink of a full coal phase-out – four years ahead of schedule. Power utility company Helen officially decommissioned its Salmisaari plant in Helsinki on 1 April, dropping coal to a less than 1% share of the country’s energy mix. Since 2020, coal generation has dropped by 73% from 2.44 terawatt hours to 0.67. Over the same span, wind power has more than doubled since 2020 to supply a quarter of the country’s energy.

Renewables account for 92% of new power capacity worldwide in 2024

/

Countries added a record amount of renewable power in 2024, according to an analysis from the International Renewable Energy Agency. The analysis found that solar is by far the fastest-growing form of renewable power, amounting to 77% of new capacity, with wind in a distant second at 19%. Continuing its clean-energy dominance, China installed more renewable power than all other countries combined last year. Still, growth is not on pace to meet a global goal to triple renewable capacity by the end of this decade.

Chinese researchers develop new battery recycling process that recovers 99.99% of lithium

/

The groundbreaking method, developed by researchers from Central South University, Guizhou Normal University, and the National Engineering Research Center of Advanced Energy Storage Materials, employs a unique ‘battery effect’ mechanism. The process achieves remarkable recovery rates: 99.99% of lithium, 96.8% of nickel, 92.35% of cobalt, and 90.59% of manganese, all within just 15 minutes. Unlike traditional methods, this approach avoids harsh chemicals and minimizes environmental harm, generating effluents suitable for use as fertilizer.

California now has more EV charging ports than gas nozzles

/

California has steadily amassed its EV charging network with both public and private charging ports over the last few years. In 2024, California boasted 178,500 total EV ports compared to around 120,000 estimated gas nozzles, according to the California Energy Commission. The number of accessible chargers across California has nearly doubled since 2022. Since August, the last time these figures were publicly updated, the state has recorded roughly 26,000 additional publicly accessible EV chargers.

Canada to build massive, fully electric, 185-mph inter-city rail network

/

Canada is set to begin work on a high-speed inter-city rail network – the largest infrastructure project in the country’s history. Spanning 621 miles, the fully electric new rail network will serve 18 million people – nearly half of Canada’s population – across the Toronto-Quebec City corridor. It’s expected to serve 13 times more passengers annually than the current service. Canada is expected to invest nearly $3 billion USD over the next six years to bring the project to light.

France runs fusion reactor for record 22 minutes

/

Achieving the dream of commercial fusion power is the Holy Grail of engineering and has been for 80 years. With a single gram of hydrogen isotopes yielding the energy equivalent of 11 tonnes of coal, a practical fusion reactor would hold the promise of unlimited, clean energy for humanity until the end of time. France has upped the ante in the quest for fusion power by maintaining a plasma reaction for over 22 minutes – 25% longer than the previous record set by China in January 2025.
